Image forming device and paper transporting method used in the same

摘要

An image forming device and a paper transporting method are capable of improving a paper transporting path by establishing a transfer drum, a developing unit, an optical unit and a paper feeding unit in four quadrant directions centering around a photosensitive drum unit, Thereby, the optical unit is protected from mechanical shock or vibration. Jamming of paper adhered to the transfer drum is easily rectified, and the overall structure of the device is simplified.
